Objective To explore the effects of early food intake on recovery of patients with postoperative upper urinary tract. Methods One hundred and twenty-six patients after upper urinary tract surgery from January to December 2012 were divided into early food intake group ( food intake beginning 6 h after surgery) and conventional group ( food intake began after first flatus ) . The recovery time of gastrointestinal function, hospital stay, drainage volume and other parameters in two groups were compared. Results The time of flatus, leaving the sickbed, defecation, stopping transfusion and getting right time of eating were (1. 80 ± 0. 46), (1. 45 ± 0. 51), (4. 06 ± 1. 10), (3. 27 ± 0. 85), (3. 33 ± 1. 16) d in the early food intake group better than those of the conventional group (t=3. 598, 2. 239, 4. 722, 3. 140, 3. 395;P<0. 05). Conclusions Early food intake after surgery of upper urinary tract can promote recovery of gastrointestinal function and decrease fluid infusion and hospital stay.

Objective? To understand the situation of urinary incontinence and quality of life among patients with post-laparoscopic radical prostatectomy and to analyze the correlation between them. Methods? From September 2015 to October 2016, we selected 115 patients with post-laparoscopic radical prostatectomy at a ClassⅢ Grade A hospital in Beijing for survey by questionnaire with the method of convenience sampling. We collected patients' general information as well as disease information, and evaluated the situation of urinary incontinence (incidence and severity of urinary incontinence) with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and influence of urinary incontinence on quality of life with the Incontinence Impact Questionnaire (IIQ-7) to analyze the correlation between severity of urinary incontinence and quality of life. Results? Among 115 patients with post-laparoscopic radical prostatectomy, there were 95 (82.6%) urinary incontinence patients including 41 cases (43.1%) with mild urinary incontinence, 47 cases (49.5%) with medium urinary incontinence and 7 cases (7.4%) with severe urinary incontinence. The score of severity of urinary incontinence ranged from 0 to 19.0 with 8.0 for the median and 5.0 for the interquartile range. Spearman correlation analysis showed that the score of IIQ-7 had a positive correlation with the severity of urinary incontinence (r=0.674, P＜0.01), and had a negative correlation with the postoperative time (r=-0.215, P＜0.05). Multiple linear regression analysis showed that the main influencing factor of quality of life was severity of urinary incontinence (P＜0.01). Conclusions? Urinary incontinence is common among patients with post-laparoscopic radical prostatectomy mainly in mild and medium urinary incontinence. The more serious the urinary incontinence is,the greater the influence on quality of life is which points out that the scientific and effective management by medical staff for urinary incontinence can improve patients' quality of life.

Purpose: This study aimed to establish whether computed tomography (CT)–determined sarcopenia is a useful imaging biomarker for postoperative outcome in elderly colorectal cancer (CRC) patients, and construct sarcopenia-based nomograms to predict individual outcomes after surgery. Materials and Methods: CT imaging data of 298 elderly CRC patients who underwent surgery in 2012-2014 were retrospectively analyzed. Skeletal muscle mass was determined by CT, and sarcopenia was diagnosed based on the optimal cutoff value determined by X-tile program. The correlation between sarcopenia and risk of preoperative nutrition and postoperative complications was evaluated. A Cox proportional hazards model was used to determine survival predictors. Sarcopenia-based nomograms were developed based on multivariate analysis, and calibrated using concordance index and calibration curves. Results: A total 132 patients (44.3%) had sarcopenia based on the optimum cutoff values (29.9 cm2/m2 for women and 49.5 cm2/m2 for men). Sarcopenia was an independent risk factor for preoperative nutrition (p < 0.001; odds ratio [OR], 3.405; 95% confidence interval [CI], 1.948 to 5.954) and postoperative complications (p=0.008; OR, 2.192; 95% CI, 1.231 to 3.903). Sarcopenia was an independent predictor for poor progression-free survival (p < 0.001; hazard ratio [HR], 2.175; 95% CI, 1.489 to 3.179) and overall survival (p < 0.001; HR, 2.524; 95% CI, 1.721 to 3.703). Based on multivariate analysis, we produced four nomograms that had better predictive performance. Conclusion CT-determined sarcopenia is a useful imaging biomarker for predicting preoperative nutritional risk, postoperative complications, and long-term outcomes in elderly CRC patients. The sarcopenia-based nomograms can provide a scientific basis for guiding therapeutic schedule and follow-up strategies.

Objective:To construct the content framework of the rehabilitation management application (APP) for patients with urinary incontinence after radical prostatectomy, so as to provide an effective network management platform for the rehabilitation management of patients wither urinary incontinence after radical prostatectomy.Methods:From November 2020 to May 2021, the content framework of rehabilitation management APP for patients with urinary incontinence after radical prostatectomy was initially constructed through literature review and group discussion. The objective sampling was used to select 15 experts from Beijing, Shanghai and other regions for two rounds of expert consultation, to construct the content framework of rehabilitation management APP for patients with urinary incontinence after radical prostatectomy.Results:Among two rounds of expert consultation, the effective recovery rates of the questionnaires were all 100.00% (15/15) , and the expert authority coefficients were 0.937 and 0.934, respectively. The Kendall harmony coefficients of all indicators in the second round of expert consultation ranged from 0.208 to 0.333, and the differences were all statistical (all P<0.01) . It was finally determined that the content framework of rehabilitation management APP for patients with urinary incontinence after radical prostatectomy included 3 first-level indicators, 10 second-level indicators, 43 third-level indicators, and 62 fourth-level indicators. Conclusions:The content framework of constructed rehabilitation management APP for patients with urinary incontinence after radical prostatectomy is highly scientific and practical, and can provide corresponding evidence.

OBJECTIVE：To establish a method for the content determination of to tal flavonoids from Amomum tsao-ko ，and to optimize the purification technology by macroporous resin. METHODS ：The content of total flavonoids was measured by HPLC. The determination was performed on Eclipse Plus C 18 column with mobile phase consisted of acetonitrile- 1％ acetic acid solution （15∶85，V/V）at the flow rate of 0.8 mL/min. The column temperature was 40 ℃，and the detection wavelength was set at 256 nm. The sample size was 10 μL. Taking the adsorption and desorption performance as indexes，6 kinds of macroporous resins were screened out by static adsorption and desorption tests ；adsorption and desorption time were investigated by static adsorption and desorption kinetics tests. Using the content of total flavonoids （calculated by rutin ）as index ，with sample concentration ，sample pH，ethanol volume fraction and elution amount as factors ，based on single factor test ，orthogonal design was used to optimize the purification technology of total flavonoids from A. tsao-ko ，and validation test was performed. RESULTS ：The linear range of rutin were 0.028-0.281 mg/mL（r＝0.999 9）. The limit of quantification was 437.5 ng/mL and the limit of detection was 109.4 ng/mL. RSDs of precision ，stability and reproducibility tests were all lower than 2％；the recoveries were 96.24％-99.75％（RSD＜2％，n＝ 6）. The comprehensive capacity of adsorption and desorption of HPD 450 macroporous resin was the most suitable ，and the best static adsorption and desorption time both were 12 h. The optimal purification technology was 1.854 4 mg/mL ； ethanol elution was 8 times of the column volume. Vertificationtests show that after optimized ，the content of total flavonoids from A. tsao-ko increased from 22.556 7 mg/g to 57.728 2 mg/g. The purity of was 2.56 and stable for the content determination. Optimal purification technology is stable and feasible ，which is suitable for purifieation of total flavonoids from A. tsao-ko .
